Hey all, had a breakdown this weekend and wanted to get it out, see if anyone has some advice or anything.

I havent made new friends for a few years, but i got a new job and there are a lot of people there, and i've started making office friends. One girl in particular that i work with I've started to like a lot, more than just a friend thing. Were starting to become really good friends, to the point where she's come over to my house to hang out. My anxiety and depression started to get a little better when I was hanging out with her.

This last weekend though, her and i both went to another co workers house to chill, and she started flirting with this other guy and i started having a panic attack that was so bad i threw up and had to go home. I barely know this girl and i dont like her THAT much, but seeing her with him made me feel like my whole world was going to end. I really dont even think that dating someone you work with is a very good idea, but for some reason i cant stand to think of her being with someone, it's like i want all of her attention to be focused on me. That, or my anxiety gets to an overwhelming point.

The best part of all of this is that she already has a boyfriend and probably wasnt even flirting with this other co worker we were hanging out with, i just saw it that way for whatever reasons, to make me feel even worse. Jealous, i think, to the point of insanity. There really was no chance of us dating or anything, but because of this feeling im scared that i'm going to end up doing something stupid to ruin the chances of even having a friend, which is something i desperately need at the moment. I just want to know why i'm freaking out so much over this girl, who i've only been working with for 2 months and barely know, and why i cant seem to control it.

I dunno, any thoughts? Thank you for reading.
